Advice or help please i7 8700k overclock

hi guys/girls so im playing around with my we gaming rig and thought id overclock my cpu but having stability issues and cant figure out the cause components are listed below 

Arous z390 ultra 

i7 8700k

trident z 3200 cl15 32 gig ram

saphire 5700xt card

corsair 360 aio cooler

Evga 850 watt power supply

 

so i started with a low oc of 4.8 (so one over boost of 4.7)on all cores changed the vcore to turbo and upped the volts to 1.25v all booted fine ran cinebench and couple games temps good no issues so upped to 4.9 all cores and upped vaults to 1.3 same all worked fine so went to 5.0 and 1,35v again was stable tho was getting hot so went back to the 4.9 1.3v oc and thought id run prime 95 and instantly failed i tryed uping and lowering vaults no change just anything over 1.35v and i run into overheating issues i tried the  low 4.8 same thing no mater what oc i try or volts to overheat prime fails straight away on small ftp test. games and cinebench, heaven bench etc all run fine but the fact prime instantly fails worry's me 

i followed several well known tutorials on youtube on a mild stable oc for my cpu but defiantly not stable according to prime any help or things to try would be great .. if i have to go back to auto no overclock then i will as builing a 3950x but would like to get a stable oc on this

Don't throw away a 8700k for a 3950x, that just doesn't make much sense... Unless what you are doing is extremely mutlithreaded. In which case, an OC on a 8700k won't matter at all compared to a 3950x. So, either way, that just doens't make much sense. Your 8700k is a great CPU, no reason to ditch it yet.

 

That said, P95 is a bit of a crazy test. I agree, I would want my system to be stable with that as well, but I would suggest trying AIDA64 and only selecting the FPU test. This is a much more "real world high end" test. Cinebench R20 is good for quickly testing stability, but its WAY to quick to really know anything beyond "it maybe be stable for a minute".

 

Run AIDA64 FPU for a few hours and see if its stable. I had a 8700k @ 5 GHz and it was a beast. Especially for gaming, a 4.8+ 8700k will beat a 3950x in almost every game. Ryzen is amazing, but very high clocked Intel chips do still pull ahead in gaming. That said, if you were to be building a new machine right now, yea a 3700 is a great value, its shockingly amazing value actually. But my point here is, no reason to dump a 8700k, its still a perfectly capable chip. Check with AIDA, and if its not stable put a little more volts to it. I am surprised its having heat issues, my 8700k did 5 GHZ at 1.300v and ran in the 70's and 80's in AIDA64. I am on a custom loop, but still.... If you are at 90-95c in AIDA, thats pretty much expected. That isn't what it will be in games. My 9900k is low 90's in AIDA, and high 50's in games........

awsome thanks  my 3950x will be my work horse the 8700k will be my gaming rig ill try the aida64 , i just watched a video on that program and aparently alot of the errors come from avx or fpu in aida and adjusting the avx oset can fix the errors

so i downloaded it with the 4.9oc at 1.3v avx offest of -1 its running fine on aida64 no errors or heat issues max temp hit 70 so far thats with stress  cpu stress stress ftp stress cashe and stress system memory yet prime errors instantly so random .. so im guessing aida will show any errors like prime

My go to software's is real bench. Try that, if there is a error it will stop the test, also dont use all of your ram in realbench.

Do just the FPU. That pushes it harder, more like prime. I was able to pass 22 hours of all of those selected at 5 GHZ @ 1.248 vcore, wasn't even able to do 4.9 GHz with just stress FPU and ~1.255 vcore. So try just the FPU test and see what happens. It will also run warmer. But 70c is solid, it will likely get up to ~82-85 with just FPU.

Realbench is also solid. I recommend trying both. AIDA64 FPU for ~8 hours, and real bench for as long as it goes (I think it has a 8 hour limit? its been so long I forget)

I like realbench because it's a bit more intense than A64, free, and stresses both your cpu memory and GPU.
